Title
(EN) Combustible ice mining leakage simulation and environment parameter quantitative inversion system and method
(ZH) 可燃冰开采泄漏模拟及环境参数定量反演的系统与方法
Abstract
(EN) The invention provides a combustible ice mining leakage simulation and environment parameter quantitative inversion system and method. By controlling opening and closing of a reservoir dynamic separation system, a combustible ice reservoir and an overburden sediment layer have separation contact dynamic capability; and the effect that methane gas only remains at the combustible ice reservoir in the combustible ice synthesis period is guaranteed. When the combustible ice is decomposed, the reservoir dynamic separation system is opened; and the combustible ice reservoir and a sea mud layer can realize natural contact, so that the whole process that the methane gas is naturally leaked into the seawater environment from the combustible ice reservoir in the combustible ice mining process is simulated through the in situ natural inversion on the overburden sediment layer and the seawater environment. The function of studying quantitative analysis of leakage modes and behaviors by different mining methods and in different modes is realized; the leakage controllable mining technologies and schemes are further optimized; and the basic data scientific principle support is provided for the green and safe mining of the combustible ice in the future.
(ZH) 本发明提供的一种可燃冰开采泄漏模拟及环境参数定量反演的系统与方法,通过控制储层动态分隔系统的开闭,使得可燃冰储层和上覆沉积层具备分隔接触动态化的能力,保证可燃冰合成期间,甲烷气体只停留在可燃冰储层。可燃冰分解时,打开储层动态分隔系统,可让可燃冰储层与海泥层自然接触,从而通过对上覆沉积层和海水环境原位自然反演,模拟可燃冰开采过程中甲烷气体从可燃冰储层向海水环境自然泄漏的全过程,具备研究不同开采方法和模式下定量分析泄漏模式和行为的功能,进而优选泄漏可控的开采技术和方案,为未来可燃冰的绿色安全开采提供基础数据科学原理支撑。
